A population of animals is introduced into a new habitat with a fixed, limited amount of food and space. Which of the following represents the correct sequence of growth phases this population will exhibit as it reaches the carrying capacity?

Options

  1. ALag phase Phase of acceleration Phase of deceleration Asymptote
  2. BLag phase Phase of deceleration Phase of acceleration Asymptote
  3. CPhase of acceleration Phase of deceleration Asymptote
  4. DLag phase Phase of acceleration Population crash

Correct answer

A. Lag phase Phase of acceleration Phase of deceleration Asymptote

Step-by-step solution

When a population is introduced into a habitat with limited resources, it follows the Verhulst-Pearl logistic growth model. The population initially shows a lag phase as it adapts to the new environment and begins to reproduce. This is followed by a phase of acceleration (rapid growth) as the population size increases, and then a phase of deceleration as resources begin to become limiting. Finally, the population reaches an asymptote when the population density equals the carrying capacity (K) of the habitat, resul
